Exchange 2010 DNS setup

Greetings,

Our company currently use google for domain for email purpose. I'm currently building a MS exchange 2010 server. It will replace the google mail.

What would be the best way to migrate everything smoothly to my exchange server.

I'm a bit confused about the DNS configuration... Currently, all my dns MX are configured with Dyndns.org and it looks like this:

Mail Exchangers:       ASPMX.L.GOOGLE.COM
ALT1.ASPMX.L.GOOGLE.COM
ALT2.ASPMX.L.GOOGLE.COM
ASPMX2.GOOGLEMAIL.COM
ASPMX3.GOOGLEMAIL.COM

I'll probably need to delete all those information.. but as soon as I delete them, I lost all email activities for 24-48hours right ? the time it takes the dns to propagate.

I also read that I need to configure a reverse DNS. How can I do this.

I don't want my server to be blacklisted.

Server name : gutenberg.domain.local

Just make sure that your external DNS is configured as per my guide here and you should be good to go: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2370-Exchange-DNS-Configuration.html

Thanks for the guide, it seems pretty complete.

I still have another question...

I have a custom dyndns account with multiple A record for accessing multiple (dynamic IP) remote offices.

At my main office, I have a windows 2008 server with dns server.

I need to create a new zone using the domain name registred with dyndns. Lets call it domain.COM

My issue is that I can't access anymore every host registred with custom dyndns since the zone exist in my windows 2008 dns server. (domain.COM)

How could I configure my windows 2008 server to find every A record in my custom dyndns account ?

Thank you

I really don't know, and to be honest, that is a seperate question.  You need to open a new question for that.
